PRINTS is a collection of protein fingerprints, derived by the excision of conserved motifs from manually-crafted sequence alignments and refined by iterative dredging of a SWISS-PROT/ TrEMBL composite database.

For ease of interpretation of results, we have elected not to include fragments in PRINTS. Mechanisms for incremental update of PRINTS based on current releases of SWISS-PROT and TrEMBL are under development, so some sequences will not be found in PRINTS, even though they are clear family members. To confirm the identification of your sequence, please try the FingerPRINTScan suite.
